Ancient Y-DNA discussion: no J2a in pre-Bronze Europe?

UPDATE 10 November 2014: The publication of DNA data from Neolithic to Iron Age Hungary did make a revision of this article necessary, as the sample BR2 (ca. 3,200 years old) was found to be positive for J2a-M67-CTS3261 (Kandell T.). His autosomal analysis lets suspect that he descends mainly from Western ancestors with no near connections to Anatolia Caucasus or […]

Minimal reference J2 phylogeny

The makers of the mtDNA reference phylogeny (Mannis van Oven, et al.) did setup a “minimal reference” for the Y-DNA haplogroups. Team members are in contact with Mannis to achieve an updated and optimized J2-M172 minimal  reference: . Primary goals of www.phylotree.org/Y/: […] optimal  global  discrimination capacity  based  on  a  strongly  reduced  set  that  includes  only  the  most  resolving  Y-SNPs. […]

J2 phylogeny in 1000 Genomes Project

Under the lead of Greg Magoon a group of citizen scientists (including J2-M172 team members Bonnie Schrack and Chris Rottensteiner) were involved in the analysis of a high-resolution a priori maximum parsimony Y-chromosome (“chrY”) phylogeny created from data of 1292 male samples in the 1000 Genomes Project. 63 of those samples are in haplogroup J2-M172 (42 in J2a and 21 […]
